Protective effects of melatonin therapy in model for neonatal hyperoxic lung injury.

Context: Bronchopulmonary dysplasia (BPD) is a common outcome of premature birth. Currently, no effective preventive therapy is available for BPD, but the major role of O2 toxicity in the development of BPD has gained attention, particularly for developing new antioxidants for prevention. The major protective mechanism of melatonin (MT) includes free-radical scavenging activity and activation of the cyclooxygenase-prostoglandin enzyme system.
